A District man was sentenced to 40 years in prison Thursday for the 2010 slaying of a man who authorities say was shot in the face in Southeast Washington.

D.C. Superior Court Judge Russell F. Canan sentenced Marlon Williams, 34, in the Sept. 13, 2010, killing of Min Soo Kang, 37, of Fairfax County. According to prosecutors, Williams was identified after he stole Kang’s 2010 Cadillac Escalade after the shooting. The vehicle was equipped with OnStar GPS tracking, which enabled police to locate the vehicle. Prosecutors said that Williams’s prints were found in the vehicle.

Prosecutors said Williams shot Kang about 4:30 a.m. in the 3500 block of Croffut Place SE. Kang was shot multiple times in the chest, face, finger and forearm.

Williams was charged with first-degree murder and was found guilty by a jury after a trial in July.
